I've said this here before. I took used perlite from a grow, put it in a large container and just hosed the shit out of it. Most of the roots floated to the top except the chunks that were really entwined with root matter. Those I just threw away Then I let it dry and put the perlite back in a 3 gallon hempy bucket and stuck some basil in there. It's now the most massive basil plant I've ever seen. Very fragrant and vigorous. It has a sibling I stuck in dirt right next to it. That plant is pathetic in comparison. I'm pretty sure I won't grow basil any other way from now on. I've never reused perlite for MJ though. But there's really no reason why you couldn't.
I don't think you really want to boil your perlite in H2O2. How much perlite are you talking about? 15 gallons or so if you are me. You'll need a great big pot and a lot of hydrogen peroxide. Also, I'm thinking hydrogen peroxide would break down pretty rapidly if you boil it. It might just be cheaper to buy new. My $.02
I have about 10 gal of perlite, I thought boiling it seemed a bit extreme. If that's all I need to do then it looks like I'm about good to go. I'll be transplanting within the next few days, prob over the weekend, I'll post some pics.
